By Clip Syndicate

Britain's intelligence chiefs will give their first ever public testimony on Thursday when they are cross-examined together in parliament about the case of former U.S. spy agency contractor Edward Snowden. The evidence-gathering session comes amid calls for the government to step up oversight of its three main intelligence agencies after documents that Snowden leaked to the press exposed Britain's role in secret mass surveillance programs.
